So I have forced air, and how we consolidated space/equipment is to use a combi tankless boiler that handles both DHW and SH - basically there's two circuits for hot water. One goes to the taps, and the other goes to a radiator/heat exchanger thing that basically goes where a furnace would but is 1/3rd the size. Fan blows over the radiator/heat exchanger = hot air out of the vents. My gas bill is quite low overall, and so is my electric. Around $50-70 dollars per month for Fortis.
